  1. Biomass The power of using plant and animal waste to generate energy By Evan Schafer, Jacob Carrick, and Maggie Weaver Room 7

  2. Introduction to Biomass • Biomass is the use of plant and animal waste to generate electrical energy. • Biomass has supplied far more renewable electricity, until recently, called biopower, which has more power than wind and solar power combined. • Biomass is low in carbon, so it is significant source of renewable energy. • Biomass has two types of reusable fuels called Ethanol and Biodiesel.

  3. How Biomass Energy is Made 1. Plant and animal waste, wood, crops, and trees are collected together into a truck. 2. The materials are then taken to a biomass power plant. • The materials are then crushed and fed into a furnace where they are burned. • The heated materials are used to boil water. • Then the energy from the steam is used power turbines and generators.

  4. Where are Biomass Materials found? • Biomass materials can be found in several different areas. Some areas include… • In the soil • In animal and plant waste • Forests • Lumberyards • Sewer systems

  5. Equipment Needed to Collect and Make Biomass • Gasifiers • Boilers • Silos and fuel tanks • Traveling screws • Shovels • Heat exchangers • Crops, wood, or waste

  6. Six Advantages of Using Biomass • Possibly could decrease the amount of air pollution • Can reduce the use of fossil fuels • Costs a small amount locally • Can convert waste into fuel • Is a renewable energy • Is more powerful than several other energy sources

  7. Six Disadvantages of Using Biomass • Large areas will have to use significant amounts of biomass, causing a huge reduction in supply • Some materials aren’t available year round • Could cause a scarcity in trees • Geography limits the ways of using biomass • It takes more energy to plant and harvest the crops • Biomass collection is hard-working and difficult

  8. Biomass Fun Facts • About a half of the renewable energy produced in the United States comes from biomass sources, such as wood and paper. • In Wisconsin and Iowa, biomass energy is being used from landfills and dairy farms. • Also in Iowa, a crop called switchgrass is being used in power plants to make electricity.

  9. More Biomass Fun Facts • Biomass supplies 14% of the world’s energy consumption. • Biomass means natural materials. • When heating and cooking were discovered by burning wood, biomass began. • Wood was the biggest biomass energy provider in the 1800’s.

  10. History of Biomass • Biomass has been around since man first used fire but it started to be used as an energy source around the world in the 1800’s. • In the late 1800’s, gasifiers were starting to be used with engines for power generation. • In the early 1900’s, fuel oil, wood, and coal were huge producers for biomass energy.

  11. History of Biomass Continued… • By the mid 1900’s, electricity and natural gas were starting to become the main producers for biomass. • In the 1980’s, America began to build and use biomass power plants. • Today, over 100 countries in the world use biomass for 10.5% of total energy consumption, according to the International Energy Agency.

  12. Where are Biomass Power Plants? • Most biomass power plants in the United States are found in California. • Also, another large biomass power plant industry is in Maine. • Around the world, many other plants are found in the Eastern Hemisphere, such as Asia and Europe. • Besides the U.S., Germany is probably one of the largest biomass industries in the world.

  13. What’s Keeping Biomass From Widespread Use? • Workers must be hired to collect biomass materials and the cost of paying the workers makes getting biomass materials harder. • Equipment such as trucks to collect the materials, gasifiers, and boilers cost a lot of money. This makes getting the equipment to create biomass more difficult. • They are still discovering different ways to use biomass and the best way of using this energy could still be discovered.
